When viewing the Technical Program schedule, on the far righthand side
is a column labeled "PLANNER." Use this planner to build your own
schedule. Once you select an event and want to add it to your personal
schedule, just click on the calendar icon of your choice (outlook
calendar, ical calendar or google calendar) and that event will be
stored there. As you select events in this manner, you will have your
own schedule to guide you through the week.
You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.

ABSTRACT: Exploiting the performance of today's microprocessors requires intimate
knowledge of the microarchitecture as well as an awareness of the
ever-growing complexity in thread and cache topology. LIKWID is a set of
command line utilities that addresses four key problems: Probing the
thread and cache topology of a shared-memory node, enforcing thread-core
affinity, measuring performance counter metrics, and
microbenchmarking for reliable performance bounds. LIKWID stands out because it is
easy to install and use and works with any Linux 2.6 kernel. LIKWID has
low overhead and is designed to be easily extended by the user.
Our poster will briefly introduce all LIKWID tools. The use of
likwid-perfctr is demonstrated using two examples: Detection of NUMA
problems and use of the likwid marker API. A ccNUMA bandwidth map for a
four socket AMD Magny Cours node shows one possible application of likwid-bench.
